The operation handle 21 is now operated to move the slider along the struts 27, 28 by means of a pulley and a rope 42.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hide gauge that is installed on a surface plate or the like and used to measure the height of an object to be measured or to mark it.

Conventionally, in order to fully move the slider that is slidably installed on the support column, in conventional hide gauges, the slider must be directly gripped and moved up and down, or the handle attached to the slider can be fully rotated. By doing this, the pinion connected to the handle is rolled and moved along a rack provided on the column.

However, the former method applies a bending force to the support column, while the latter method applies vibration, which has the drawback of causing dimensional errors and other problems for a hide gauge that performs high-precision measurements. In addition, in the latter case, the operating force of the handle acts on the binion and rack, causing them to wear out.
This has the disadvantage of increasing backlash and reducing measurement accuracy and sharpening accuracy.Furthermore, since slider moving parts such as a handle and pinion are attached to the slider, the weight of the slider increases. This leads to problems such as complication of the internal mechanism, etc., and furthermore, in order to prevent the support from deflecting due to this increase in weight, the support must be made strong, which increases the total weight of the entire hide gauge, making it difficult to use. Moreover, it also has the disadvantage of increasing manufacturing costs. In addition, in both the former and the latter, since the operating piece Mr moves up and down as the slider moves,
In the case of large hide gauges, it is necessary to change the measuring attitude, which is also disadvantageous in that it is not easy to use.

Furthermore, in conventional hide gauges, the base on which the struts are planted and fixed is relatively small, and this base is not provided with a special gripping part, so the hide gauge cannot be mounted on a surface plate. When moving the hide gauge in parallel or to a separate position, it is necessary to touch the support directly or indirectly, which may cause deformation of the support, which is unfavorable in terms of measurement accuracy. There is also a drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide a note gauge that allows marking operations and dimension measurements to be carried out with high accuracy and efficiency.

The present invention achieves the above-mentioned purpose by providing a slider assembly base for operating a moving mechanism that enables the slider to move along a support column, thereby making it possible to move the slider with only a hand operation on the base. This is what we are trying to achieve.

Hereinafter, a second embodiment of the present invention will be described based on the drawings.

A first pulley 22 is inserted into the other end of the long shaft 20 and fixed with a key (not shown), and a first pulley 922 is attached to the other end of the long shaft 20. A protrusion 20B is formed by protruding from the base. This protrusion 20
B is inserted into the through hole 25 of the short cylindrical 20th rotating body 24, and these protrusions 20B and the rotating body 24 are rotatably connected by a bearing 26. 1 Said No. 1. The outer diameters of the second rotating bodies 17.25 are formed to have the same dimensions, and in the portions of the same dimensions, the first rotating bodies 17.25 each have a round bar shape. A second strut 27°28 is installed. The first of these. The second struts 27 and 28 are formed to have the same length, and the distal ends of these struts 27 and 28 are fixed by a connecting member 29 so as to remain parallel to each other.

A through hole 29A penetrating the upper and lower surfaces in FIG. 1 is formed in the center of the connecting member 29.
A second pulley 30 is rotatably supported within 9A via a shaft 31. At this time, this second pulley 30
The rotation center axes of the first pulley 22 and the first pulley 22 are arranged so as to be parallel to each other.

A relatively short round bar-shaped supporting leg 32 is provided on one side of the bent connecting member 29 so as to protrude perpendicularly to both the connecting member 29 and the struts 27 and 28. As will be described later, the tip end of the support 27.28 is dimensioned so that the support 27.28 is brought into vertical contact with the surface plate 10 in the most reclined state, and the support 27.28 is held in the horizontal direction in this state. (See figure 2 ridge line position)
.

The slider 33 is attached to the pillar 27.28.
8 is slidably supported along the longitudinal direction.

A scriber 34 is removably attached to one side of the slider 33 via a fixture 35, and the amount of displacement of the slider 33 along the pillars 27 and 28 is displayed in analog and digital form on the front surface of the slider 33. A movement displacement amount display device 36 is provided. This display device ft3
6 is of normal structure, for example, branch office 2T or 28
A pinion (not shown) that meshes with a rack (not shown) provided in the slider 33 is built into the slider 33, and the number of rotations of this pinion is counted and displayed. The device 33 can be reset to zero at any position.

Further, the scriber 34 can be replaced with a scribing needle if necessary.

The slider 33 has a support 27°28
A slider clamp 37 that can be fixed at any position is provided, and this clamp 37 has a structure that can be fixed by pressing the tip of a screw passing through the slider 33 into contact with the circumferential surface of the support column 27. .

Furthermore, the slider 33 has a column 27.2 of the slider 33.
A minute feed adjustment device 38 is provided which allows for minute feed movement adjustment along 8. This minute feed adjustment device 3
8 is a substantially short cylindrical feed tube 39 slidably provided on the support column 27, a fixing screw 40 for fixing the feed tube 39 to an arbitrary position on the support column 27, and a part of the feed tube 39 attached to the feed tube 39. The feed cylinder 39 is attached to the support column 27 by the fixing screw 40 with the cam surface of the eccentric cam 41 in contact with the slider 33. By fixing the slider 33 to a fixed position and then rotating the eccentric cam 41 by a predetermined amount, the necessary minute feed movement adjustment of the slider 33 can be performed.

One end of a rope 42 as a flexible transmission member made of twisted steel wire or the like is fixed to the front side of the lower surface of the slider 33 in FIG. 1 via a compression coil spring 43.
The other end of the slider 33 is wound around the first pulley 22 about one turn and then extended in one direction, and is further provided with a small hole vertically penetrating the rear side of the slider 33 in FIG. (not shown) is movably inserted into the upper second boot 9.
The rope 42 is wound around the rope 42 about half a turn and extended downward, and is fixed to the front side of the upper surface of the slider 33.
is formed in an endless shape (loop shape).

In other words, the slider 33 is fixed in the middle of the endless rope 42, and is configured to move as the rope 42 rotates.
This can be done by rotating the pulley 22 with a handle 21 through a long sleeve 20-karat gold wire. Here, the first. Second pulleys 22, 30, long shaft 20, handle 21, rope 42 as a flexible transmission member, and spring 4
3 constitutes a slider moving means 44. Further, the compression coil spring 43d is a relatively strong spring,
The tension of the rope 42 is sufficiently strong, and the rope 42 is locked with strong frictional force between each pulley 22° 30, especially the first pulley 22, which is wrapped around one and a half turns, to prevent slippage and longevity. .

On the outer periphery of the cylindrical convex portion 17A of the tenth rotating body 17,
A V-shaped small groove 45 is formed all around the circumferential direction, and a female thread 46 is formed in the gripping member 12 at a position opposite to this small groove 45, and a tightening bolt 47 with a sharp tip is formed in this female thread 46. The sharp tip S of the tightening bolt 47 that is screwed together can be engaged and pressed into the small groove 45, and this pressed state allows the first rotating body 17 to
can be fixed to the gripping member 12 at any angle. In addition, when the tightening bolt 47 is slightly loosened, the tip of the tightening bolt 47 is in the small groove 45, so that the tightening bolt 41 is attached to the gripping member 1 of the first rotating body 1T.
2 is stopped in the axial direction. Furthermore, a handle 48 is detachably provided on the head of the tightening bolt 47 to facilitate operation of the tightening bolt 47. Here, the small groove 45, the female thread 46, the tightening bolt 47, and the handle 48 constitute a first inclination angle setting means 49.

Further, on the end of the outer periphery of the gripping member 12 on the tenth rotating body 17 side, there is a scale portion 50 (
The scale portion 50 and the pointer 51 provided on the tenth rotating body 17 constitute an angle display device 52 that displays the entire inclination angle of the columns 27 and 28.

Several tapered fixing holes 53 are bored in the outer circumferential surface of the cylindrical convex portion 17A of the first rotating body 17 toward the central axis direction of the first rotating body 17. The central axes of the measurement holes 53 are formed at a predetermined angle with each other (see FIG. 4). A tapered tip of a fixing pin 55 inserted through a through hole 54 formed in the gripping member 12 is inserted into these fixing holes 53 without a gap. In each state in which the fixing pin 55 is fitted into each fixing hole 53, the first rotating body 17 is attached to the gripping member 12.
That is, the first support 27 installed on the first rotating body 17 is set at a predetermined angle, for example, 0 degrees, with respect to the surface plate 10.
It is configured to be fixed at commonly used inclination angles such as 30 degrees, 45 degrees, 60 degrees, etc. (see FIG. 4). Further, these fixing holes 53, through holes 54, and fixing pins 55 constitute a second inclination angle setting means 56.

Here, the slider moving means 44 and these first . The second inclination angle setting means 49 and 56 are constructed so that they do not interfere with each other during their operation. That is, the first pulley 22 in the slider moving means 44 is locked by a strong frictional force to the rope 42 which is stretched sufficiently strongly by the action of the spring 43, and the first pulley 22 is connected to the long axis 20f. , since the first
Alternatively, the second inclination angle setting means 49 or 56 may be used to adjust the support column 27 to an arbitrary angle or a preset angle.
28, the first pulley 22
4 by the same angle rt, hence the rope 4
2, the first pulley 22 does not produce any rotational noise, so the slider 33 does not move relative to the support column 27.
6, the slider moving means 44 is not interfered with at all.

On the other hand, by operating the slider moving means 44, the first and second
It is clear that the inclination angle setting means 49, 56 are not interfered with because the first rotating body 11 is fixed to the gripping member 12.

Next, the operation of this embodiment will be explained.

Measurement of height along the vertical base line and raking work along the horizontal base line are performed in the same way as with conventional hide gauges, but with respect to the vertical base line or horizontal base line. When measuring along a direction in which a predetermined inclination angle is met, the following procedure is performed.

From the state in which the columns 27 and 28 are installed in the direction along the vertical base line, the fixing pin 55 of the second inclination angle setting means 56
After completely removing the handle 48f of the first inclination angle setting means 49:
When the tightening bolt 47 is slightly loosened by operation, the first rotating body 1T becomes rotatable with respect to the base portion 14. On this occasion,
By leaving the tip of the tightening bolt 47 in the small groove 45, it acts as a stopper to prevent the first rotating body 17 from being pulled out in the axial direction, so the tightening bolt 47 is prevented from being loosened too much. Further, since the second rotating body 24 is always freely rotatable about the long axis 20, the columns 27, 28, etc. are brought into a free state by the above-described operation. In this state, by directly supporting the pillar 27.21 and using it as the angle display device t52', tilt the pillar 27.28v to a desired angle of inclination, and then tighten the tightening bolt 47, so that the first rotating body 17 It is fixed to the pace part 14, and the struts 27, 28 are fixed at a predetermined angle of inclination. When setting this inclination angle, as described above, the slider moving means 44
Although the tilt angle setting means 49.56 do not interfere with each other, the slider 33 does not move relative to the support columns 27.28.

Next, grip the gripping member 12 of the base portion 14 and remove the surface plate 10.
The scriber 34 is brought into contact with the measurement surface of the workpiece, and the operation handle 21 is operated to move the slider 33 through the long shaft 20, the first pulley 22, and the rope 42 to the support column 2.
7.28, the displacement amount of this slider 33 is displayed by the displacement amount display device 36, so that the dimension of the measurement surface in the direction of a predetermined inclination angle can be measured.

In addition, with the tightening bolt 47 loosened, use the fixing pin 55 of the second inclination angle setting means 56 to insert it into an appropriate fixing hole 53 among the plurality of fixing holes 53 set in the first rotating body 17. By inserting the fixing pin 55, the first rotating body 17 is fixed to the base m14 at a predetermined angle with a single touch, and this also allows the inclination angle of the columns 27 and 28 to be set. Directional measurements are taken.

In addition, when measuring dimensions along the horizontal baseline,
As in the case of using a conventional hide gauge, the entire base portion 14 may be slid on the surface plate 10, or the surface plate 10 may be slid on the surface plate 10.
Without moving the position of the upper base part 14,
The support leg 32 is brought down to a position where it touches the surface plate 1°, and in this state, the slider 33 is lowered along the support columns 27 and 28.
may be moved.

Note that when scribing using this embodiment, it is possible to carry out the scribing work in the same manner as in the past, by removing a scribing needle instead of the scriber 34 and moving the slider 33 in this state. In addition, when scribing an arc on the scribing surface of the workpiece, the scribing needle is brought into contact with the scribing surface while the slider 33 is fixed at a predetermined position on the soil with the slider clamp 37. All you have to do is change the inclination angle of the pillars 27 and 28. Furthermore, in the above-mentioned sharpening work and workpiece measurement work, the support 27 of the slider 33
．． If a minute amount of feed along the line 28 is required, a minute amount of feed adjustment device 38 is used. That is, this is done by fixing the feeding tube 39 to the support column 27 with the fixing screw 40 and then rotating the eccentric cam 41.

After completing the measurement work in this way, when storing the hide gauge of this embodiment, the gripping member 12 can be moved without touching the parts such as the supports 27 and 28 that may affect accuracy.
grasp, transport, and store.

According to this embodiment, the following effects can be obtained.

The operating handle 21 for moving the slider 33 is located on the base portion 1.
Since the slider 33 is attached to the gripping member 12 of No. 4, the weight of the slider 33 is lighter compared to a conventional slider in which a handle for direct movement is attached to the slider. Since the center of gravity as a whole is lowered, it is possible to create a hide gauge with good workability. Also, when operating the handle 21, the slider 3
Since the vibration of the slider 33 is eliminated, wear and damage of the rack, etc. inside the slider 33 can be prevented, and a decrease in precision in marking work and dimension measurement can be prevented.

Furthermore, when rotating the handle 21, the pillars 27°28
Since force is not directly applied to the support columns 27 and 28, deformation does not occur in the support columns 27 and 28, and from this point of view as well, it is possible to effectively prevent a decrease in measurement accuracy and the like. In addition, when performing measurement work at a large incline, the stability of the hide gauge is unavoidable, but even in such a situation, when rotating the handle 21, direct force is applied to the supports 27, 28'Jk. Since the work can be done without having to act on the slider, the base part 14 will not be moved by mistake, and the difficulty of operating the handle when tilting in the conventional case where the handle is fixed to the slider can be solved. The column tilting function can be made more effective.

In addition, since the gripping member 12 has a cylindrical shape, it can be easily manufactured from an easily available round bar, and it fits easily in the hand and can be easily gripped. In addition, this makes it possible to improve the operability when sliding this hide gauge on the surface plate 10, and in addition, at this time, it is possible to slide the hide gauge on the surface plate 10 without touching the supports 27 and 28. Since the supports 27 and 28 can be slid, deformation of the supports 27 and 28 is not caused, and a decrease in precision in dimension measurements can be prevented. Furthermore, when transporting this hydraulic gauge, it is only necessary to grip and transport the gripping member 12, so it is possible to prevent the deterioration in the mounting accuracy of the pillars that would otherwise occur due to transporting the pillars with money. .

Since the handle 21 is directly attached to the gripping member 12, the hand position can be switched between horizontally moving the base 11 while gripping the gripping member 12 and operating the handle 21 in a short time. Since all work can be done in one place, work efficiency can be improved, and there is no need to change the working posture, making work easier.

Furthermore, the gripping member 12, the first pulley 22, the first and second
Since the rotating bodies 17 and 24 are arranged in series with the same axis, the means for transmitting the rotational force of the operating handle 210 to the first pulley 22 is the long shaft 20, which is quite simple. I can do it. Further, since the gripping member 12 and the rotating bodies 17 and 24 have the same outer diameter, the appearance of the base portion 14 of this hide gauge is simple and can be made into an excellent shape.

Furthermore, since the first pulley 22 has the rope 42 wrapped around it one turn or more, the first pulley 22 and the rope 42
The rotational operation of the handle 21 can be reliably transmitted to the slider 33. Also, rope 4
2 is always biased to be tensioned by a tension spring 43, so even if the rope 42 stretches due to long-term use, the tension spring 43 absorbs the stretch and the rope 42
The tension state of the handle can be maintained effectively, and from this point of view, the handle 2
Ten rotations can be reliably transmitted to the slider 33. Further, the first pulley 22 is connected to the base portion 14 and the second
Since it is rotatably supported by the rotating body 24 of the holder 24 through the bearing 19° 26, the tilting movement of the pillars 27 and 28 and the moving movement of the slider 33 do not interfere with each other.
Very easy to use. Further, since the slider moving means 44 is structured to include the rope 42, the support columns 27.2
It is no longer necessary to provide a transportation rack on column 8, and column 2
By 7°28, the overall weight can be reduced completely.

Furthermore, since the supporting legs 32 are provided, there is an effect that measurement and scraping work in the horizontal direction can be performed in an extremely stable state.

Since the columns 27 and 28 that fully support the slider 33 are composed of two cylindrical bodies, the rigidity of the columns 27 and 28 remains constant no matter what the tilted state, allowing accurate marking work and measurement. It has the effect of being carried out.

In addition, by inserting the fixing pin 55' into the fixing hole 53, it is possible to easily and accurately set the predetermined inclination angle with respect to the support column 27.28Th surface plate 10 with one touch without looking at the angle display device 52. can.

In the above embodiment, the supports 27 and 28 are made up of two cylindrical bodies, but the number of pillars may be one or five or more, and the shape is not limited to a cylindrical shape but may also be a prismatic body. It may also be a flat plate.

Further, although the supporting legs 32 of the connecting member 29 are provided protruding only on one side, supporting legs may be provided protruding on both sides.
Horizontal scraping work, etc. on both sides of the base portion 14 is possible. At this time, it is more effective to provide the movement displacement amount display device 36 on both the front and rear sides of the slider 330. moreover,
The minute feed adjustment device 38 is not limited to the structure using the eccentric cam 41, but may be structured using a feed box, a feed screw, a feed nut, and a fixing screw conventionally used in general hide gauges.

Further, although the tension spring 43 for keeping the rope 42 in a constant state of tension is provided outside the slider 33, the same effect can be obtained even if it is constructed as a built-in type as shown in FIG. That is, a small hole 61 is formed on the upper surface of the case of the slider 33.
One end of the rope 42 inserted through this small hole 61 is fixed to a locking member 62 made of a small screw, and this locking member 62 is screwed into the first receiving plate 63 and is tightened with a nut 64. A compression spring 6 is fixed between the first receiving plate 63 and the second receiving plate 65 which is in contact with the inner surface of the slider case.
6 is interposed, and the rope 42 may be biased so as to be constantly pulled by this compression spring 66.

Furthermore, a catch having a concave portion in which a cylindrical inner circumferential surface slightly larger than the outer diameter of the rotating bodies 17 and 24 is formed is placed on the base 11 so as to be able to slide on the outer circumferential surfaces of the rotating bodies 17 and 24. In this way, the weight of the support columns 27, 28, etc. is supported by the seats, so that the accuracy of the support columns 27, 28 relative to the base 11 can be effectively maintained for a long period of time.

Further, the operating handle 21 is located at one end of the long sleeve 20, that is, at the first end.
Although the handle 21 is attached to the right end in the figure, it may also be attached to the other end, that is, the left end in FIG. Often, the operating handle 21 may be provided on the upper surface or other peripheral surface of the gripping member 12 by means of a groove, a pair of bevel gears in the middle of the long shaft 20, or the like. In addition, if the handle 21 is attached to the left end of the long shaft 20 and there is only one support, this support is fixed to the first rotating body 17, and the second
If the rotating body 24 is fixed to the base 11, the long shaft 20 can be stably supported in a so-called dual-supported state.

Furthermore, the base 11 and the gripping member 14 constituting the base portion 14 may be integrally formed by casting or the like, and in this way, the number of parts can be reduced.

Further, the movement displacement amount display device 36 does not necessarily need to have both a digital display and an analog display, and
The display driving method and display method may be electrical, magnetic, or optical.

Furthermore, the first. Both of the second inclination angle setting means 49 and 56 do not necessarily need to be provided, and only one of them may be provided as necessary. Furthermore, the structure is not limited to the above structure, and other structures such as a collet chuck type or one using a worm may be used. Moreover, the rope 42 as a flexible transmission member is preferably made of twisted steel wire with little elongation, but is not limited to this and may be made of other materials.

According to the present invention as described above, it is possible to provide a node gauge in which the slider can be moved by hand and there is no need to hold a support or the like when moving the hide gauge.
